After months of bitter fighting stemming from Kody’s favoritism, the wives’ long-held grudges and Meri’s humiliating catfishing scandal, the Brown family is in an all-out war.

“It’s worse than ever. The family is arguing constantly,” Kendra says. “They pretend to be happy for the show, but the family is a mess."

In fact, Kendra reveals that Kody is “definitely seeking another wife right now. He wants a younger female, basically what Robyn used to be.”

Kendra claims that Kody propositioned her, in front of Robyn, to become his fifth bride.

“The first time he met me he said, ‘You’re so pretty. I’m looking for another wife!’ Robyn was laughing, but I was like, 'Eww!'”

“He’ll most likely drop one of the other wives,” Kendra says, claiming that TLC plans to pull the plug on Sister Wives after season seven. “Kody’s main goal is to keep the series going and to make money. He’s a snake.”

Kendra goes into detail about each of the wives’ relationships with Kody, stating that “Kody thinks of Janelle as more of a friend — she’s his buddy. Christine is just a brat and a problem to him,” adds Kendra. “And Meri, Kody can’t stand her.”
